IMPROVEMENT IN WELT-GAGES FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 158,231, dated December 29,1874; application file'd September 1, 1874.

To all whom it may concern Be it known that I, FRANCIS D. BALLOU, of Abington, Massachusetts, have invented a Welt-Gage Attachment to Sewing-Machines,

"inachine, by which the welt-strip is continuous] y presented to the needle at a proper gage, and the upper applied to it at a proper gage, with great facility.

In the drawing, Figure 1 is a section, and Fig. 2 an end elevation of this combination.

a is a plate, either the bed-plate of the machine or one applied to it specially for the purpose; and his the needle-throat. A lip, k is turned up at a proper gage from the throat h for the projection of the welt beyond the seam, uniting the welt w and upper to. A plate, 1), adjustable, to and from the lip k by means of the slot 9 and clamping-screw d, serves as a against the edge of the plate 0, and the stitches thereby set at a proper gage.

I claim as my invention, and desire to secure by Letters Patent- In combination with the plate a, provided with the needle-hole h and lip W, the plates 1) and a, secured to and made longitudinally adjustable upon said plate, substantially as and for the purpose specified.

FRANCIS D. BALLOU. Witnesses:
